Specification of Letters Patent.

Application filed, December 8, 1920. Serial No. 429,080.

To 07. 21710712. it time concern:

Be it l IDOWU that I, ERNEST Donner, a subject (it the King oi Great Britain, and resident of the city oi Toronto, county of York, Province of Ontario, in the Dominion oi Canada, have invented certain new and useful It proveinents in Boxes, described in the following specification and illustrated in the accompanying drawings, that form part oi? the same.

'lhc principal objects of the invention are to overcome the difficulties met With in the removal of covers from the small. type of tin boxes used for polishes, salves, pills, etc, and to devise a term of box which may be sealed perfectly tight but from which the cover may be released without dilticulty and without inarring or distorting the box.

'ihe principal feature of the invention consists in placing a remomble ring between the cover and the box so that when the ring is removei the cover will be loose.

In the accom iianying drawings, Figure 1. is a pers iective view of a box constructed according to this invention, showing the cover sealii'lg ring in the sealed position.

i igure 2 is a )erspective ViGW of the ho showing the sealing ring withdrawn troni the cover.

Figure 3 a cross sectional View of the box showing the 1'5 11;; in the sealing position.

The hot; i is of? a simple cylindrical type haw/hug the straight side walls 2. The cover E is formed with the edge flange having a larger internal diameter than the external diameter oi the box. The space between the voter and box is closed by means of a sealring which (its tightly therebetween makiugan air tight joint if desired and this ring is tormed with a lateral flange G which extends outwardly below the bottom edge oi" the cover.

When it is desired to remove the cover l'rom the hon: it is merely necessary to press dowuwarrilly upon the flange oi' the ring 5 and Withdraw the ring "('0111 between the cover and the box, which thus leaves the cover ouite free so that it may be lifted otl' aliowin tr 3 access to the contents.

When it is desired to replace the cover simply laid on top and the flange ring drawn upwardly between the cover and the body of the box or it may be found easier to move the ring up to the top of the box and lit the cap thereover.

C'ihc provision of this sealing ring renders the removal oi the cover an extremely simple o'iattcr'. it is cheap to cons ruct, easily as scmhled and easily operated. Further, such a device will not be susceptible to damage through careless handling but Will retain its working qualities as long as the box.

The box herein shown is oi a very simple cl aracter, having straight sides, but the de iu n oi the box may of course be varied and t strengthening; beads are required they may placed on the inside instead of on the out s is the practice in the present "forms 11:" boxes.

lihat I claim as my invention is In a box, the combination with the body and cover having its flange loosely surroundng the bijidy, of a removable ring arranged .aetvyeen the cover flange and the side Wall of the body.

2. A box having a cylindrical side Wall, :1 (-o 313i" h aving a flange fitting loosely around said side wall, and a sealing ring of thin metal 2U. apted to lit between the side Wall of the ho): and the loose flange ot' the cover and to l 'fillll a sealed joint, said ring having a bottom edge flange projecting beyond the cdgg c oi the cover flange.

ERNEST DOBNEY.
